SPECIFIC-GRAVITY REGSTER.

Application filed November te n the specific gravity ot niill and other ceL tain liquid products, especially gasoline,

ia a mani 1 so that consumers may obsei've if the product varies from its proper standz'rd ot value or specitic gravity, in order to avoid using adulterated and contaminated liquid, such as when kerosene or other in iter'ioii' products are mixed with gasoline.

lhe invention contemplates the provision ot a casing' which may be applied to any means :tor conveying the liquid from a source ol' supply to a receiving receptacle such as the inlet ot the fuel tanli of an automobile or other motor driven vehicle, and the cashas elements providing an inlet and an ourlet for the gaseous fuel to flow therethrough when a supply is delivered to the tank. rilhe inlet and outlet are relatively arangcd whereby a portion oit the liquid will be retained in the casing, and i'otatively supported in the casing is a countei'balanced displacing body ot a weight whose specilic gravity is approximately similar to the specific sity ot the liquid when ot a standard density, said body being submerged in the liquid i'or being moved by the buoyant elli'ort ot the retained liquid when of a density lvarying from its known standard oi density, On the casing is an indicator which may be ot a torni including a movable scale oiE sp-ecii'ic gravity measurements or symbols and associated with the scale is a pointer which is movable with the movement ot the displae ing body lor indicating the relative diii'erence of density of the liquid during its ilow through the casing.

'Other objects ot the invention are to proAA vide in the casing an auxiliary outlet lead ing to the main outlet 'lier discharge ot 'the liquid retained in the casing;v liollowing the cessation ot the llow therethrough, to provide a valve for controlling the opening and closing ot the auxiliary outlet; to provide 13, 1925. Serial No. 68,864. means tor moving the valve from the auxili 'y outlet and ttor separating and yieldiiigly holding the displacing body and its eooperating parts from their normal supports in the casing; and to provide means for keeping the scale in a determined position with respect to the pointer independent ot the position ot the easing. y

llVith these and other objects in view, the invention will be hereinafter more fully described with reference to the accoinpanying` drawings forming a part ot this specilication in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end ot the description.

'lhe apparatus has a casing l() which may be oi" any suitable size and shape, though the iorin ot the easing illustrated is substantially rectangular to provide bottoni wall 11, side walls l2, 13., a rear wall la, a top wall l5 and a liront wall 1G which is removable` to allow the working parts et the apparatus to be assembled and mounted in the casing. On top ot the easing l0 at its front wall 16 and between its side walls 1:2, 13 is a box or chain: bei' l? having' a iront wall i8, rear wall 19, eine walls E20, 2l and an upper wall 22. ln t e upper wall 22 of the boi; 17 is an opening which is closed by a plate ot glass 23 to provide an observation window, and part oil the portion oli the top wall l5 of the casing l0 forming th e bottom wall of the box 17 may be con caved or curved clownwardly to torna a recess, as at 2li- The part ci" the top wal"L ot the casing in proximity to the recess 24 may be cnlaiged to provide a boss or bearing, as Q5, having its passage leading into the interior ol the casing l0. llllithin the casing at the corner oil' its side wall 12 with the rear wall le: is a curved partition or wall 26 providing an inlet 27 having its entrance leading v charge pip e 32.

through the top wallA of the casing into a pipe, as 2S, having its upper portion exterior-ly threaded, as at 29. Also in the casing` l() Vat the corner of its side wall i3 with the rear wall 14 is another curved partition or wall 3() providing,` an outlet 3l havingl its exit leading` through the bottom wall 1l into a discharge pipe, as?,v 32, protruding below the casing. The partition 25 is of a length so that the inlet 27 terminates in spaced relation to the bottom ll of the casing, and the partition 30 is of such a length that 'the upper part of the outlet 3l terminates in spaced relation to the top wall l5 of the casing. rllhe portion oi' the interior-ot the casing below the upper end of the outlet 3l provides a chamber 33 for retaining a portion of liquid when llowing;l through the Casino. On the underside of the bottom wall ll or the easing l0 is a duct, as 34, having its passage leading` from an opening or auxiliary outlet b5 in the central part of the bottom -wall to the passage Voic the dis- 'llo the central part of the side wall 13 at the front wall 16 is secured, at 36, one end ot' a bracket 3l' of such a length that its other end terminates approximately midway between the side walls, and on the free end of this bracket is a substantially U- shape-d bearing, as 38, having' the bottoni wall of its recess formed in somewhata tl-shape, as Vat 39. On the inner face-ot the rear wail 14 of the casingis a similar substantially tlshaped bearing, as 40, also having the bottom wall of its recess formed in somewhat a V- shape, as at-4l, and both of the bearings 3S and 40 are on alinement with the entrances of their recesses in opposed relation to the top wall 15 of the casing.

rIhe bearings 38 and 40 support a removable rotative beamy or shaft 42 having' on its ends approximately V -shaped knife edge 'pivots or bearings 43, v44 which are inovably seated in the il-shaped parts 3S, 4l oit the re cesse-s of the bearings 33, 40. Vllhe rotative beam 42 is yieldingiy held rotatively in the bearings 38, 40 by means of a spring;l 45 in the formv of a 'flat strip of metal having' one of its ends fastened, at 46, to the parti n wall 26 off the inlet 27 of the casing', and the other end of the spring presses upon the beaui with the spring having a thrusting yielding pressure upon the beam to prevent `accidental displacement of the beam from the bearings 33, 40 when the beam is under upwardl pressure. The beam 42 carries a displacing body 47 which vmay be in the form oi a hollow subv stantially spherical shaped body providing an air chamber, and this dislnacing` body 47 is of a weight whose specitic `eravity is approximately similar to thespecific: gravity the liquid when of a standard density. E2;- tending?T from part of the floator air chainber is a bar 48 having on its other end a sleeve 49 which is adjustably carried en the beam 42 in proximity to the: knife edge bearing;` 43 of the beam, and a set screw 50 passed through a threaded hole in the sleeve into engagement with the beam 'for tightening the sleeve to the beam when the. displacing,` body is in an adjusted position. Projecting Ytroni the. sleeve 49 is a bur 5l having on its other end a weight or ball 'llhe bars and 5lY are disposed on downward diverging iuclincs providing` a substantially V-shaped lever, and the ball 52 and its bar 5l are ot weights with the ball having a specific gravity for counterbailaneing the displacing)v body 47 and its bar 4S. Duringy the ilow or liquid through the casing l0 troni its inlet 27' to and through the outlet 3l the part ot the chamber 33 below the mouth oi' the outlet 31 will retain a portion of the liquid and the displacing' body 47 and weight 52 will. be submerged. ills above ei;- plained the displacingf body is ot such specilic gravity that if the liquid olf a standard specific gravity or density the displacing; body will not move, but if the liquid *aries in specific gravity lroin its recognized standard of density value the displacing body will by the buoyant eilort oli the liquid rise or lower tor rotatively moving the beam 42 accordingly.

in the box l? ot the casing' is a registerili;r device 53 for iinlicatinnl the dillierence ol speciiic gravity or density of the liquid flowing arough the casing to determine it the liquid varies from its recognized standard of density since the device is designed ior testing liquids, such gasoline, milk or other licluids the grade or quality `value ot which are established by lined standards ot specilic gravitiesW The registering device 53 niav be oi any suitable type, though the forni olE ihc roeisteringidevice shown has an arc-shapcd or curved plate 4 which is positioned with one ol its faces exposed to view through the window 23 of the box l?. @n the exposed fare oil' the plate 54 is a scale. of spaced ineasu se ments in the 'terms of appropriate characters or markings, 56, Vfor indicating' the relative d` 1erence of density oil" the liquid flowing: the c h as compared with its dens or specific 2erafvit'v. F or example if the rice is used for testing' graso line its standard specific gravity oi' 0.2" should be inscribed, as a; 5?, Fin. l. on the plate at one oi the ineasru'enient niarlrings 5G oit the scale and the other markings are adapted to indicate it the gasoline flowing' through the casing;r varies in density value from its standard specific lgravity. as will be hereinafter more fully explained. ln pari ol' the plate 54 opposite to the .scale 55 is au opening and protruding.;` Yfrom the lince oit the plate opposite to the. scale mai,T be a sleeve 5S which surrounds the edge ol" the opening. fl' '-fre end ol1 the sleeve 58 is au annular vith a seginientul bevel part opposite lo its :i tud 6l which ri 1 rear 5S) niesh i, Gl, having; its teeth held on one enr o journaled in a bearing, as 62, provided on one end of a bracket, as 63, having' a sleeve G4 projecting downwardly frein the underside oi' its second end. The passage el' the sleerewleads through the bracket G3, as Well as being in register with the passage oit the annular bevel near 59, and the sleeve Gil is slidably disposed through the lined bearing` et the bei: ll' so that the lower portion et the sleeve ext-ends into the chainber 33 ot' the casingl l0. On the bracket 63 surroiuuling1 its opening which communicates with the pas sage of the sleeve Glis another sleeve on the upper end ei' which is inovably suiiported the annularl bevel gear 59, and the passage ot the sleeve is in register with the opening; through the bevel rear 59. Rotatable in the sleeve 58 ol' the scale 59, annular bevel gear 59, sleevev65 and sleeve Gli is a shaft 6G oit a length so that its upper end protrudes above the plate 54 of the scale 55 and so that its lower end extends below the sleeve Gl in proximity to the beain l2 otl the float fl?. On the upper end of the shatt GG is lined one end of a pointer 67 which is dis-iposed with its other end directed toward the scale tor in'dicatiiig the speeiiic gravity n'ieasurenunts 56 of the scale when the shalt 66 is revolved. ln proximity to the lower end of the sha-lit @il is held a bevel rear 68 which meshes with a bevel `@gear '(39 held on the bearu l2 of the :float il so that with the upward or downward inoveinent oi the lloat the bevel gear G9 and bevel gear 68 will rotatively nieve to revolve the shaft G6 and adjustably swing' the pointer 6T across the measurements oit the scale 55.' rihe scale 55, bevel 59, seujn'iental bevel gear 60 and stud (il are operative independently ot the operation et the pointer G7, and on the stud (il is held one end oit a bar 7() having on its other end a weigi'ht or ball Tl which may bernovably disposed in the recess 24 ot the top wail l5 et the casing. ',lho ball 7l is o'l a weight 'tor yieldingrly holding the stiul 6l, segniental bevel `rrear 69 and bevel grear 59 ior holdingl the scale 55 in a determined position with respect to` 'the poii r independent ol" the position oil' the casing. That is, it the device is tilted the casini;- l0 and box 1T will assume inclinul positions, and the tloat (i7 with its counterbalancingr weight 52 will by reason ot gravity cause the beain l2, bevel gears G9, 5Fl and shait G5 to o ierate accordino'l f for retainino the a cross bar 73 erterulinsl toward the front wall i6 and rear wall la oil' the casing` 10, and this cross bar is ot a length nearly siinilar to the length oi the beani a2 oi the tloat 4T. Projecting downwardly 'troni the ends ot the cross bar 73 are two rods Tdi, i' 5 having their lower ends terininatinil with hook ineinbers 76, 77 respectively. The parte of the beain 4t2 et the float 4T adjacent the bearings fill, all are rotatively disposed in the hook nieinbers 76, 77 of the rods Tl, 75; ln part ol the cross bar i3 above the auxiliary outlet 35 of 'the chamber 33 ot the casing; is an opening through which is slidably disposed the upper end oit the stein *i9 et a valve F9 tor controlling; the openingy and closing; ot the auxiliary outlet 35. 'lhe central portion oit the stern 78 of the valve i9 is also slidably disposed through abearingiI 'oll provided on the rear wall le olf the casi g, and on the upper end olf the stein oit the valve may bea lined collar 91 iter limiting; the downward n1ovenient oi the stein and valve in the cross bar 'F3 and in the bea-rino; 80, Enoircling` the stein T9 is a springl 92 having` one oil' its ends pressing' upon the valve and having;` its other end pressingz,` agaiinist the bearing' 99 tor servinggtonormally torce the valve 'i9 yielrlingly on its seat in the auxiliary outlet 35 oi the casing' 'tor cansino' a portion o'l the fluid ilowing;- through the casingl to be retained in the charnber 33.
